President Obama has called for stricter federal gun laws to combat recent shooting rampages, but a review of recent state laws by The Washington Times shows no discernible correlation between stricter rules and lower gun-crime rates in the states.

States that ranked high in terms of making records available to the National Instant Criminal Background Check System also tended to have tighter gun laws — but their gun-crime rates ranged widely. The same was true for states that ranked poorly on disclosure and were deemed to have much less stringent gun-possession laws.

For example, New York, even before it approved the strictest gun-control measures in the country last week, was ranked fourth among the states in strength of gun laws by the Brady Campaign to End Gun Violence, but was also in the top 10 in firearm homicide rates in 2011, according to the FBI.

Meanwhile, North Dakota was near the bottom in its firearm homicide, firearm robbery and firearm assault rates, but also had some of the loosest gun laws and worst compliance with turning over mental health records to the background check system.

Analysts said the data underscore that there are no simple or easy broad answers to combating gun violence, which is a complex equation involving gun-ownership rates, how ready authorities are to prosecute gun crimes and how widely they ban ownership.
